i have read your problem. Tha's good that your MRI and EMG are normal. You have not mentioned your age and whether you feel weakness in you limbs or not. however it could be symptoms of BFS(benign fasciculation syndrome
). this is a benign condition and doesnot lead to any harm. if we correlate you heart beat with fasciculation this could be anxiety disorder, which is episodic and leads to sudden increase in your heart rate
. you should also do ECG and TFT's to rule out any thyroid related illness. your blood CBC profile indicates acute neutrophilia
which occurs in acute infection.
i may help you more if you further elaborate your symptoms and complains like if there are any tremors in hand, feeling of heart beat any other associated illness, increased appetite, shortness of breath
, any numbness in hands and feets etc.
waiting for your reply
